FLAT-SURFAGE-PRESSURE DEVICE.
Specification of Letters Patent. I
PatentedAug. 12, 1919.
Application filed August 21, 1916. Serial No. 116,215.
To all whom it may concern:
Be it known that I, CHRISTOPHER T. CLARK, a citizen of the United States, residing at East Shore Park, in the county of Washington and State of Minnesota, have invented certain new and useful Improvements in Flat-Surface-Pressure Devices, of which the following is a specification.
One object of my invention is to provide a roller for use in squeezing out and compressing newly laid mastic floors or streets.
Another object of my invention is to provide a smooth surface to be applied to the material being worked, so that no joint lines will be printed on the surface.
Another object of my invention is to provide means for heating that portion of the roller adjacent to and pressing on the material that is being worked.
Another object of my invention is to provide a floor or street heating means that will maintain a given amount of heat on a particular section of the floor or street for a definite length of time while the heating means 1s moving.
With these and incidental objects in view the invention consists of certain novel features of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawing which accompanies and forms a part of this specification.
In the drawing Figure 1 is a side elevation of the preferred form of my improved device as exemplified in a caterpillar roller.
Fig. 2 is a plan View of the same.
Fig. 3 is a perspective View of a portion of a modified form of roller. Fig. 4c isa similar view of a second modification, and Fig. 5 is a section taken on the line A A, Fi 1.
flournaled in the frame 1, Fig. 1, main shafts 2 and 3, each carry three sprocket wheels 4, 5 and 6, as better shown in Fig. 5.
These bars are of such dimensions that they shoulder against each other where the chain is traveling between the sprocket wheels, and hence make the chain rigid in one direction, but flexible in the other direction where it follows around the sprocket wheel.
It is apparent, therefore, that if the chains carrying the bars 8 are suitably driven, the lower surface of all the bars on which the weight of the machine is being carried will be in one plane.
A belt 9, preferably of thin metal, is carried by rollers 10 at the back of the machine, rollers 11 at the front, roller 12 at the top of the machine, and suitable tension is established in the-belt by the idle roller 13 carried by the spring 15, which is mounted at 16 to the frame of the machine and maintains a continuous upward pressure of the roller 13 against the belt.
A suitable motor 17 drives the shaft 2 through pinion 18, gear 19, pinion 20, gear 21, pinion 22, through the shaft 2 to which the sprocket wheels are keyed.
It is evident that the rotation of the motor 17 will drive the roller either forward or backward, depending upon the direction of the rotation of the motor, the caterpillar chain laying a continuous track for itself on the endless belt, which is also laying a track for the caterpillar chain.
The result of this construction is that when the roller is in operation, the floor or street on which the machine is being used is sub ected to proper pressure by a flat surface, and not merely by a line of contact as is the case in the ordinary type of roller.
and 25 to the tank 26, provide means for continuously heating the bars 8 when the machine 1s in use, and by heating these bars in their upper as well as in the lower position, a substantially uniform heat is maintained at all times.
A steering roller 27 connected to the frame of the machine by the yoke members 28 and pivotally mounted at 29 t0 the y Provides means for steering the machine, either by riding on the machine and operating the handle 30, or throwing the handle 30 forwardly and walking in front or behind the machine.
As an alternate construction, I provide suitable bearings for rollers 31, Fig. 3, in
the frame of the machine and pass over these rollers the endless belt 9, so that by placing the rollers sufliciently close together, I provide a substantially fiat pressure surface by means of the belt.
I also sometimes employ instead of rollers 3, skids 32, which support the endless belt 9 longitudinally, and by placing these skids close together obtain a substantially flat pressure surface by'meansof the belt.
In either of the modifications, I provide a pipe 33 with nozzles 34 forh eating" that portion of the roller directly applied to the flooror street: v
While I have described my invention and illustrated it in one particular design, I do not wish it understood that I limit myself tothis construction, as the application of my invention may be varied in many ways within the scope of the "following claims;
Claims:
